"They're fucked now..." Muttered in a movie theater at a point in the show when imminent doom descends upon a group of characters. Or, if it's only one person, HFN or SFN for "He's fucked now" or "She's fucked now".

Dan: "Ha ha! The bomb's gonna go off on 15 seconds and they just dropped the wire cutters down the sewer drain!"
Bill: "Ha ha! TFN!"

Gary: "Hanging onto the cliff with bloody fingernails, and the bad guy steps up with a shotgun. HFN..."
